Instantiate new client

require "prtg"

config = {}

config[:host] = Net::HTTP.new HOST, PORT
config[:host].use_ssl = true
config[:host].verify_mode = OpenSSL::SSL::VERIFY_NONE

config[:username] = USERNAME
config[:passhash] = PASSHASH

client = Prtg::Client.new(config)

Fetch name and objid of all sensors

client.table.content(:sensors).columns(:objid, :name)

Fetch name and objid of all sensors which have a given tag

client.table\
      .content(:sensors)\
      .columns(:objid, :name)\
      .filter_tags(:given_tag)

Get only the first

client.table.content(:sensors).count(1)

Get only the second

client.table.content(:sensors).count(1).start(2)

• Now historic data can be queried
• Client#live_data is deprecated and will be removed in the next version. The new api now maps the api's url pattern.

• Change the query 'objid' to 'id'. This reacts to changes in Prtg api version 13.2.3.1927.

• Add Accept-Encoding header to API calls. Otherwise Prtg version 13.2.3.1927 seems to faulty compress response data.
